THE SPACE

The homes at Bell Street are built new from the ground up, designed for efficient use of space, natural light, and comfortable everyday living. Every detail is engineered for performance, durability, and a modern lifestyle.




Bell Street offers three lots on the corner of Bell Street and West 46th Street in the West Plaza neighborhood.

What makes Bell Street so Different?

It's all in the details.

Every Kala home is designed and built to meet a higher standard. The homes at Bell Street are no exception, crafted to provide exceptional comfort, health, durability, and sustainability for decades longer than a traditionally built home.


The difference goes far beyond aesthetics; it’s designed into every layer and detail, from properly sized, energy-efficient mechanical systems, to thoughtful framing, and meticulous air sealing and continuous insulation. 

  • Air-tight, vapor-open envelope assembly

    Keeps your home comfortable year-round by preventing air leaks while allowing any trapped moisture to dry safely outside, ensuring long-term durability.

  • Thermally broken, triple-pane, NFRC Certified windows

    Among the best in the world, these windows provide exceptional insulation while allowing for abundant natural light—keeping you warm in winter and cool in summer.

  • High-performance entry doors

    Multi-point locks and airtight seals make these doors not only secure but also energy-efficient and incredibly durable.

  • R-28 Wall Assembly & R-70 Roof Insulation

    Superior insulation that minimizes thermal energy transfer, keeping your indoor temperature stable and comfortable no matter the season.

  • R-20 Continuous slab and foundation insulation

    A critical layer that stabilizes the temperature of your home’s foundation for enhanced energy efficiency and comfort.

  • Mechanically controlled, continuously filtered fresh air system

    Delivers exceptionally clean air certified by the EPA’s Indoor Air Quality+ standards, ensuring a healthier living environment.

  • Heat pump water heater

    An ultra-efficient hot water solution that’s as sustainable as it is effective.

  • Minimized thermal bridge design

    Reduces energy loss, prevents condensation in walls, and ensures consistent indoor temperatures.

  • EV Charge Ready

    Conveniently charge your electric vehicle in your own garage.

Bell Street isn't built like anything else on the market — because nothing else on the market is built like this. Most new construction meets code and stops there. Bell Street goes further, with a continuous, airtight building envelope, high-performance windows, and mechanical systems engineered to work together from the ground up.


The result isn't just a nicer house. It's a fundamentally different way of living in one — quieter, more consistent, and built to perform for decades, not just to sell.

Observation Row offers nine coveted lots on the eastern end of 21st street in the Westside neighborhood.
